Lewis Hamilton hopes he can continue to use his position within Formula One to push for greater diversity, saying such an achievement would be "more rewarding than any championship".

The Mercedes driver has won a joint-record seven world titles across his career, tied only with Michael Schumacher, and is widely regarded as one of the greatest in the sport's history.

Yet he has commanded just as much attention for his off-track activities in recent years, with the Briton leading anti-racism and pro-LGBTQ demonstrations within F1.

Speaking ahead of this weekend's Saudi Arabian Grand Prix – where he protested against anti-LGBTQ laws last year – Hamilton revealed he hopes to thrive in continuing to push for broader change.

"That's my role here I think to continue to hold those conversations, sit with Stefano [Domenicali] and say what are you doing and how can we work together?" the 37-year-old told Sky Sports.

"It goes back to bringing people on the journey rather than calling people out and unfortunately it takes a lot of yapping, but I think people seem more keen to be on the journey together and they empathise more with it and say yes, we can do a better job.

"I've got this platform and I am able to apply pressure in an uncomfortable way sometimes, but also it is a real opportunity to spark that change and that for me is more rewarding than any championship.

"My goal is that in the next five, 10 years you're looking back at the sport and I am watching TV, hopefully with my kids, and they see young women engineers and mechanics and they'll know there is an opportunity."

Having lost the 2021 F1 World Championship to Red Bull's Max Verstappen in controversial circumstances, Hamilton was denied a record-breaking eighth title.

But while winning honours remains a motivation for Hamilton, he feels such feats do not move the needle on the matters he wishes to help solve.

"I think as I started getting older, I started thinking I am winning these championships but what does it really mean?" he added.

"I realised that these championships are very rewarding personally, but they're not changing anything.

"You have another credit to your name, but it doesn't change the world, it doesn't change the fact we still have wars, we still have racial injustice.

"There are still people being abuse, there are all sorts of things out there, so what are we going to use this medium for, what are we going to use this platform for?

"I guess I really discovered my purpose – it's not just being a racing driver."

Za'Darius Smith has agreed a three-year deal with the Minnesota Vikings, according to reports.

The 29-year-old became a free agent after being released by the Green Bay Packers, and has now signed on with their NFC North rivals.

Reports suggest Smith's contract in Minnesota will have a base value of $42million, and potentially be worth up to $47m with incentives.

He had been expected to return to the Baltimore Ravens last week – whom he left for Green Bay in 2019 – supposedly agreeing to a four-year, $35m deal, but later pulled out.

In the days following Smith's apparent signing, both Von Miller and Chandler Jones – who are several years older than Smith – signed contracts with the Buffalo Bills and Las Vegas Raiders respectively, worth nearly double the annual salary of the deal offered by the Ravens.

The versatile edge rusher recorded 18.5 sacks in four seasons in Baltimore after he was drafted in the fourth round in 2015.

He then racked up 26 sacks across his first two years in Green Bay, helping them to back-to-back NFC Championship Game appearances.

However, a back injury limited him to just one regular-season appearance in 2021. Smith returned for the Packers' Divisional Round matchup with the San Francisco 49ers, but could not prevent a 13-10 defeat.

The Buffalo Bills have brought in running back Duke Johnson and wide receiver Jamison Crowder.

AFC East winners the Bills, who have been rated as the early Super Bowl favourites for 2022, continue to be active in free agency.

Having previously brought in star pass-rusher Von Miller, they added Johnson after missing out on the signing of J.D. McKissic to the Washington Commanders.

Pass-catching RB Johnson signed a one-year deal which has now been confirmed by his agents.

He has spent time with the Houston Texans and Miami Dolphins in recent seasons but is best known for a four-year stint with the Cleveland Browns to start his NFL career.

Crowder, meanwhile, has been productive when healthy over recent seasons despite playing for the struggling New York Jets in the same division as the Bills.

The wideout has reportedly signed a one-year deal worth up to $4million, helping to fill the void left by Cole Beasley's recent release.

Crowder racked up 188 catches over the last three seasons despite missing nine games through injury.

Elsewhere, Buffalo's rivals for AFC supremacy the Kansas City Chiefs have signed wide receiver Corey Coleman.

A former first-round pick with the Browns, Coleman has not caught a pass since 2018, but the Chiefs have opted to take a flyer on the Baylor product, who was not on an active roster last season.

Fresh from their dramatic moves at the quarterback position, the Atlanta Falcons have remained active.

As well as confirming their previously reported re-signing of offensive weapon Cordarrelle Patterson, they added free agent pass rusher Lorenzo Carter, formerly of the New York Giants, on a one-year contract.

Drew Lock is relishing the chance of a "fresh start" with the Seattle Seahawks and is aware of the size of the task that awaits him after replacing Russell Wilson.

The 25-year-old has been acquired by the Seahawks as part of a deal that saw Wilson head the opposite way to the Denver Broncos.

Lock appeared in just six games for the Broncos last season, starting only half of those, but he is hopeful of getting his career back on track in a new chapter in his career.

"I was ready for something to happen, and then when I found out that this is what happened, I was really, really excited," he said.

"I'm excited for a fresh start, excited to come in and compete for a starting job and do everything I can to show this organisation and show this league what I'm capable of doing.

"I've got new team-mates, new coaching staff, new energy, new this, new that, new feel, whatever it may be, a new practice field, it's just the true definition of a fresh start.

"You get to make a new identity for everything, you get to come in and show these people how hard you want to work, how bad you want it, how bad you want to win games. 

"There's just a lot of good that can come from a new chair in a meeting room. There's a lot that goes into all this, and a fresh start for me is really, really exciting."

Lock is competing for a starting spot with Jacob Eason, the only other QB on the Seahawks' roster, and is confident of adapting to Shane Waldron's offensive system.

"I obviously know a little bit about coach Waldron's system, which is similar to the one I ran my rookie year when I first got in the league," Lock said.

"We won four of the five games, and I played efficient football, took care of the ball, scored in the red zone, hit the deep shots when they were there.

"When we start talking and getting into the deep details of his offense, we'll put it all together and end up being able to put a good offense together that makes my skill set shine. 

"I can throw the deep ball, I can move around in the pocket, I can play-action. Whatever you might need me to do, I'll be able to do it."

Lock will wear the number two jersey with the Hawks as a sign of respect for the departing Wilson, who spent nine years with Seattle.

Wilson threw for 37,059 passing yards, 292 touchdowns and 87 interceptions during his Seahawks career and he averaged 7.83 pass yards per attempt.

That is a tally only Deshaun Watson (8.32), Patrick Mahomes (8.10) and Peyton Manning (7.89) bettered among quarterbacks across that period.

He also ranked fourth in touchdown percentage (6.2) and third in passing plays of 25 yards or more (323), leaving a massive void to be filled in the 2022 season.

But while Lock is full of respect for what Wilson achieved with the Seahawks, he is out to write his own chapter at Lumen Field.

"As long as football goes on, Russell Wilson will be very special to this place, very special to Seattle," he said. 

"I know what it takes to, kind of build a legacy. You wouldn't go wear 18 in Indianapolis, you wouldn't go wear 12 in Green Bay. It's a sign of respect for him from me.

"But also at the same time, I want to write my own story here. I want to see what two does for us. I want to make that me. 

"I don't want to fight against Russell, he's done so many great things for this place and so many great things for the city of Seattle and the state of Washington. 

"I want two to be Drew, and that's just kind of been my mindset on it. 

"I have the utmost respect for him and that was a move in showing that."

Eddie Hearn thinks a world heavyweight title rematch between Anthony Joshua and Oleksandr Usyk will take place at the end of June.

Usyk outclassed Joshua to claim the WBA, WBO and IBF titles at Tottenham Hotspur Stadium last September.

Plans for a second bout have been up in the air after Usyk returned to Ukraine to defend his homeland following the Russian invasion.

Hearn, Joshua's promoter, believes Usyk will be allowed to leave his country in order to step into the ring with Briton Joshua again.

Asked whether Joshua will face Usyk next, Hearn told The DAZN Boxing Show: "I think that's the most likely scenario.

"We had those conversations about a week ago and I had my doubts as to whether Usyk would be ready, but I believe now that there’s been some kind of conversations with Usyk and even [Vasily] Lomachenko as well with the government to say 'look, how do we sit in terms of competing in major sporting events'.

"I don't think Usyk's going to want to wait, once you start waiting anything can happen, so we actually had some talks this morning."

Hearn says Joshua could take an interim fight if he is made to wait for another bout with Usyk.

He added: "I do think Usyk will take that fight next, we're looking at the end of June for that fight and that’s when the fight has got to take place by.

"If he's not ready, we'll push for an interim fight, but my gut feeling right now, and this could change is that you will be seeing Anthony Joshua v Oleksandr Usyk for the unified world heavyweight championship next."

Rafael Nadal has been ruled out of action for up to six weeks with a cracked rib suffered during last week's Indian Wells Masters.

The Australian Open champion sustained the injury in his semi-final win against Carlos Alcaraz and visibly struggled to breath during his defeat to Taylor Fritz in the final.

Nadal told reporters that he was "all good" when returning to Spain on Tuesday, but it has now been revealed he has a stress fracture in the third left costal arch.

The timeframe for the Spaniard's recovery is between four and six weeks, which could have a major impact on his preparations for the 2022 French Open.

The second grand slam of the year is scheduled to begin at Roland-Garros on May 22 – around eight weeks' time.

Nadal had won each of his opening 20 matches this calendar year, a run that took him to his second title at Melbourne Park, prior to tasting a shock defeat against Fritz.

And the record 21-time major winner, who endured an injury-plagued 2021, is now facing a battle to be back at peak fitness in time for the French Open.

Providing an update on his personal Twitter page on Tuesday, Nadal posted: "As it turns out, I have a stress crack in one of my ribs and will be out for 4-6 weeks. 

"This is not good news and I did not expect this. I am sunk and sad because after the start of the season I have had such a good time.

"I reached a very important part of the year with very good feelings and good results. 

"But hey, I've always had that fighting and overcoming spirit and what I will do is be patient and work hard after my recovery. Once again thank everyone for the support."

Nadal has won the French Open a record 13 times, with his most recent success in Paris coming in 2020.

He was beaten by eventual champion Novak Djokovic in last year's semi-finals – only his third defeat in 108 matches in the event.

Leonard Fournette has become the latest player to re-sign with the Tampa Bay Buccaneers, according to reports.

After Tom Brady made a sensational U-turn on his decision to retire, Chris Godwin also agreed to a three-year deal worth $60million with the Bucs after being franchise tagged by the team who won Super Bowl LV at the end of the 2020 season.

Fournette is understood to be signing a new three-year deal in Tampa Bay worth $21million, potentially rising to $24m.

The 27-year-old running back reportedly visited the New England Patriots, who had also shown interest in him when he left the Jacksonville Jaguars in 2020, on Monday.

However, like then, Fournette looks to have decided on the Bucs, where he enjoyed a productive 2021 season.

His 1,266 total yards from scrimmage ranked sixth in the NFL, as he rushed for 812 yards, caught 69 passes for 454 yards and scored a total of 10 touchdowns.

Fournette's 4.5 yards per carry average last season was a career-high.

His best game of the season came in the 38-31 win at the Indianapolis Colts in Week 12, scoring four TDs, making eight first downs and racking up a total of 131 yards from 24 touches.

Fournette was placed on injured reserve after suffering a hamstring issue following Week 15, but returned for the divisional round defeat to eventual Super Bowl LVI winners, the Los Angeles Rams.

The man nicknamed "Lombardi Lenny", or "Playoff Lenny", had previously put in a 135-yard performance as the Bucs won Super Bowl LV, beating the Kansas City Chiefs.

Chris Hoy has labelled Mark Cavendish's spectacular Tour de France comeback as "one of the greatest" in sporting history.

Cavendish, a silver medallist on the track for Great Britain at the 2016 Olympic Games, made a stunning return to Le Tour in 2021.

Having not featured in the race since 2018, Cavendish came in as a late replacement for Deceuninck-QuickStep and landed four stage wins, seeing him match the great Eddy Merckx's career record of 34 stage victories that had stood since 1975.

Indeed, Cavendish went into the final stage with the opportunity to surpass Merckx, though he could only finish third in a sprint finish on the Champs-Elysees. He nevertheless took the green jersey for the second time in his career.

It was an unlikely road back for 36-year-old Cavendish, who just last week became the oldest winner of the Milano-Torino.

"Oh, I think Mark Cavendish's comeback last year was one of the greatest in sport we've ever seen," Hoy, one of Great Britain's greatest Olympians, told Stats Perform.

"It was, I don't think even he had really thought that he was gonna have such an impact, and to be called in so late in the year. He had a really solid year, started winning again, he got his confidence back.

"But I don't think that he even envisaged that he would be competing in the Tour de France, let alone winning multiple stages and equalling the greatest of all time in many people's eyes.

"He's having a fantastic year this year as well, but regardless of what he does from now on he is a legend of the sport and that will not change. An extra Tour de France stage win is what he wants, but it wouldn't make him any more of a legend in my eyes.

"I'm sure for most of the cycling community his place is already cemented forever. He is a proper legend of the sport."

For Hoy, Cavendish's legacy is secured around the globe.

"I think Mark has real global appeal," Hoy said. "He's well known in the UK and has a huge following over here, but equally wherever he goes, wherever he competes, because of the way he raced, because he's so exciting, because there's always drama surrounding him.

"He either wins or there's always some controversy or something. It is great for the sport. I think the best thing about his comeback is seeing how much it means to him and the emotion, because sport is nothing without emotion.

"If somebody wins just routinely, and it becomes almost easy looking, even if it's not, but if it appears to be easy and there's no emotion, then it's hard for the public to get behind that. But for Cav, he's always had that emotion, people love to see how much it means to him.

"We've never seen Cav quite as emotional as when he won his first stage of the Tour last year, it was incredible."

Marc Marquez revealed he has been suffering from double vision again after a huge crash that ruled him out of the Indonesian Grand Prix on Sunday.

The six-time MotoGP champion hit the ground hard in a massive highside at Turn 7 during the warm-up for the race at the Pertamina Mandalika Circuit.

Marquez was left dazed after landing heavily and was taken to hospital for a check-up.

The Repsol Honda rider suffered concussion and was unable to start the first grand prix in Indonesia since 1997.

Marquez was diagnosed with diplopia following a crash in practice at the Portuguese Grand Prix last year and the Spaniard has been troubled by the same issue following his latest accident.

The 29-year-old revealed he has not suffered as badly as he did previously and did not state whether he will be able to get back on his bike for the next race in Argentina on April 3.

He tweeted on Tuesday: "It seems that I am experiencing deja vu... During the trip back to Spain, I began to have discomfort with my vision, and we decided to visit Dr. Sanchez Dalmau, who confirmed that I have a new episode of diplopia.

"Fortunately, it is less severe than the injury I had at the end of last year. But now it's time to rest and wait to see how the injury evolves."

Chris Hoy believes "fierce competitor" Egan Bernal can return to full strength despite the injuries he suffered in a horror crash earlier this year.

Bernal, who won the Tour de France in 2019 and the Giro d'Italia in 2021, was treated in intensive care following the accident in Colombia in January.

The 25-year-old underwent multiple operations after sustaining a fractured vertebra, a fractured right femur, a fractured right patella, chest trauma, a punctured lung and several fractured ribs.

Bernal subsequently revealed in a social media post that there was a "95 per cent chance" of him being paralysed or losing his life.

However, after leaving hospital, Bernal is now on the road to recovery and this month shared a photo of him training on a static bike at home.

Hoy, speaking to Stats Perform to mark 500 days until the start of the 2023 UCI Cycling World Championships in Glasgow, said he is hoping Bernal will be back competing at the highest level after a long road to recovery.

"I guess it's always hard to tell just how bad an injury or how bad mentally a big crash can affect athletes and with social media, you're always trying to portray the best possible side and the positive side all the time," said Hoy, who is one of Great Britain's most successful Olympians with six gold medals.

"But there is no doubt that no matter how well he's doing now, it will have been a huge struggle to get past the physical injuries and the psychological scars as well from such a horrible accident.

"He is a fierce competitor, all the other team-mates who know him say that if anyone can, he can, and I think the cycling community is hoping that he will get back to his very best and be able to compete on the biggest stage. But, you know, it's not a small challenge that he's facing, but we'll have to wait and see."

Four-time Tour de France winner and Bernal's former INEOS Grenadiers team-mate Chris Froome also suffered a horrendous crash in 2019, which put him out of action for almost a year.

Froome was 34 when that accident occurred, and Hoy says Bernal at least has age on his side.

"I think Bernal’s age will help, that the chances on getting back and competing at the highest level, are definitely improved by the fact that he is still relatively young," Hoy said.

"But until you get back into that real cauldron of competition you just don't know what it's going to be like and I guess the longer you're away from competing, the more that fire burns and the more you want to get back and taste that victory again."

Lonzo Ball's recovery from a left knee injury will be slowed with Chicago Bulls head coach Billy Donovan revealing they will "pull back" on the guard's rehabilitation process.

Ball, who is averaging 13.0 points, 5.4 rebounds and 5.1 assists this season, has not played since January 14 when he sustained a slight meniscus tear, which required arthroscopic surgery.

The Bulls have been without Alex Caruso in recent weeks too, coinciding with their slide down the Eastern Conference standings to fifth with a 42-29 record.

Donovan said the Bulls would pause Ball's recovery for 10 days, taking him up to April 1, leaving only five regular-season games for him to return prior to the playoffs.

"The feeling was, let's really pull back on what he's doing and let's let him, I don't want to use the word rest because it's not like he's sitting around doing nothing – he'll do strength training and those kind of things – but take a break on the running and trying to ramp him up," Donovan told reporters prior to Monday's 113-99 win over the Toronto Raptors.

He added: "We'll have a better feel of that once they get through this next 10 days. Obviously, it's coming to the end of the season.

"I think that they felt like, OK if he can, over this 10-day period, really get back to the ramp-up period, because he has been out for quite some time, that would enable him to get back into contact relatively soon.

"But we can't even get him into that until he gets over that hump, so I don't want to speculate what may or may not happen after 10 days."

LeBron James hopes former teammate Kevin Love harbours no resentment after a brutal dunk in the Los Angeles Lakers' 130-121 win over the Cleveland Cavaliers.

James' return to Cleveland saw him put up a triple-double of 38 points, 12 assists and 11 rebounds, along with the dunk on his championship-winning teammate Love.

Attacking off an Austin Reaves dish inside, the 37-year-old launched to the basket with Love underneath, and the knee in the chest only served as a punctuation mark to what was a ferocious dunk.

Afterwards, James joked he hopes the invitation to the wedding of Love - whom he played with at the Cavs from 2014 to 2018 - is not rescinded.

"It was after the offensive rebound so I was diving down the middle, and once I got the bounce pass and put my left leg down on the ground, that's when I looked up," James said at the post-game news conference.

"To be completely honest, I hate that it had to be him. He's my guy, that's my brother and I hope I'm still invited to the wedding.

"That's not even in my all-time dunks so take it out. Kevin Love, I love you. I wish I could take those two points back and we'd still win by nine."

After last Sunday's demolition at the hands of the Phoenix Suns, the Lakers have regrouped on this road trip and if not for a fourth-quarter collapse against the Washington Wizards on Saturday, would be coming back home with a three-game win streak.

James believes performances have nevertheless been encouraging, with the Western Conference play-in on the horizon.

"For about 11 quarters, we've played some good basketball," he said. "Aside from the fourth quarter in the last game, we've played some good basketball and want to continue that trend.

"Obviously we want to defend a lot better, but this team is making a lot of shots, making a lot of plays and scoring a lot of points versus everybody.

"To come into this building, where [they] have played some exceptional basketball all year, on the last game of a road trip before we head back west, it was a big game from us."

Brooklyn Nets' All-Star Kevin Durant has showered praise on upcoming opponent Ja Morant comparing him to Hall of Famers Michael Jordan and Allen Iverson.

The Nets take on Morant's Memphis Grizzlies on Wednesday, with Durant describing the first-time All-Star as a combination of Jordan, Iverson, Russell Westbrook and Derrick Rose.

Morant has enjoyed a breakout year after being pick two in the 2019 NBA Draft and leading the Grizzlies to the playoffs last season.

The 22-year-old Memphis guard is averaging 27.6 points up from 19.1 points in the 2020-21 season along with 5.7 rebounds, 6.7 assists and 1.2 steals this season for the playoffs-bound Grizzlies who have a 49-23 record.

"He's a combination of players, I feel," Durant told reporters after the Nets' 114-106 win over the Utah Jazz on Monday.

"I think the greatest players in our game can transform into anybody at any given point, and I think Ja is on the way to that. I mean when he's playing I see like two or three or four different hall-of-famers in his game.

"From Iverson, he might make a Jordan-like lay-up, he might run down the court like a Westbrook or a D-Rose. His float game is up there with some of the best that's ever played.

"I don't wanna gas him up too much since we're playing against him, but I think the sky is the limit for him. His future is obviously bright, and he makes everybody better playing against him."

On the Grizzlies, Durant added: "When you got a future Hall of Famer at the head of the snake, it just makes everybody better."

Durant scored 37 points with nine rebounds and eight assists in Monday's win as the Nets improved to 38-34.

The Nets forward surpassed close friend Jerry West (25,192 points) into 22nd on the NBA's all-time scoring charts with his 37-point haul on Monday.

"Winning the championship with Jerry, having conversations with him, knowing the history of who he is, he helped kickstart the NBA basically, it's an honour," Durant said.

"He's a legend in the game. He's almost like the godfather of our sport. Good to see him back around our game but it's even better to pass him. He's one of the all-time great players in this league."

Durant moves to 25,213 points, with Indiana Pacers legend Reggie Miller next above him on 25,279 points.
